TECHNICAL FIELD

The present disclosure relates to a system for evaluating a built-invideo recording device for a vehicle, and more particularly, to a systemfor automatically evaluating a built-in video recording device for avehicle, which is capable of automating a process of evaluatingperformance of a built-in camera system for a vehicle and improvingaccuracy and reliability.

BACKGROUND

A built-in camera system is provided in a vehicle and serves as abuilt-in driving video recording device to record a driving or parkingvideo of a vehicle. Such a built-in camera outputs video data inconjunction with an audio-video navigation (AVN) display device withinthe vehicle.

Conventionally, there was no automatic evaluation technique for abuilt-in camera system for a vehicle, and manual verification wasperformed based on all actual vehicles.

That is, conventionally, an output terminal of an actual vehiclecontroller was measured for electrical performance measurement, camerarecording performance was simply checked in an actual vehicleenvironment for recording function evaluation, and a screen wasevaluated by manually touching an actual vehicle-based AVNT (audio-videonavigation terminal) display for GUI performance evaluation. Inaddition, in the related art, it was difficult to verify visibilitydepending on a license plate distance, and it was impossible to verifyan influence of illumination/screen complexity.

As such, there is a problem in that work efficiency is lowered bymanually verifying video recording and an AVNT GUI display function ofthe built-in camera system in the prior art. In particular, there was anevaluation deviation for each test person because quantitativeevaluation was impossible as all GUI touch verification was performedmanually.

In addition, in the related art, it was difficult to implement averification environment for external environmental conditions(visibility by illumination/license plate distance) when checking thevisibility of the license plate in the actual vehicle, so the evaluationof video quality and visibility of a camera recorded video of the videorecording system was somewhat insufficient.

Therefore, recently, various studies have been conducted to automate theevaluation of the built-in camera system for a vehicle and improveaccuracy, but the study results are still insufficient. Accordingly,there is a need to develop a technology to automate the evaluation ofthe built-in camera system for a vehicle and improve accuracy.

The movement unit 270 may have various structures capable of moving thefirst touch tip 250 and the second touch tip 260 in the direction inwhich the first touch tip 250 and second touch tip 260 approach eachother or move away from each other. The present disclosure is notrestricted or limited by the structure of the movement unit 270 and themethod of operating the movement unit 270.

For example, the movement unit 270 may rectilinearly move the firsttouch tip 250 and the second touch tip 260 between a first position atwhich the first touch tip 250 and second touch tip 260 are adjacent toeach other and a second position at which the first touch tip 250 andsecond touch tip 260 are spaced apart from each other.

According to another embodiment of the present disclosure, the movementunit may be configured to rotate the first touch tip and the secondtouch tip between the first position at which the first touch tip 250and second touch tip 260 are adjacent to each other and the secondposition at which the first touch tip 250 and second touch tip 260 arespaced apart from each other.

According to the exemplary embodiment of the present disclosure, themovement unit 270 may include a base part 272, a driving source 274disposed on the base part 272, a rectilinearly movable member 276configured to be rectilinearly moved by the driving source 274, a firstlink part 278 connected to the first touch tip 250 and configured torectilinearly move the first touch tip 250 relative to the second touchtip 260 by being selectively unfolded or folded corresponding to therectilinear movement of the rectilinearly movable member 276, and asecond link part 279 connected to the second touch tip 260 andconfigured to rectilinearly move the second touch tip 260 relative tothe first touch tip 250 by being selectively unfolded or foldedcorresponding to the rectilinear movement of the rectilinearly movablemember 276.

The base part 272 is connected to an end of the articulated robot 230.For example, a flange portion (not illustrated) having an extendedcross-section may be provided at an end of the base part 272, and theflange portion may be fastened to the end of the articulated robot 230by bolting.

The driving source 274 is disposed on the base part 272 and providesdriving power for rectilinearly moving the rectilinearly movable member276.

Various driving sources capable of providing driving power may be usedas the driving source 274. The present disclosure is not restricted orlimited by the type and structure of the driving source 274.

For example, a typical solenoid may be used as the driving source 274.According to another embodiment of the present disclosure, a hydrauliccylinder (or a pneumatic cylinder) or a motor may be used as the drivingsource.

The rectilinearly movable member 276 is connected to the driving source274 so as to be selectively and rectilinearly moved by the driving powerof the driving source 274.

For example, the rectilinearly movable member 276 may be provided in theform of a rod having a circular cross-section. Alternatively, therectilinearly movable member may have a quadrangular cross-sectionalshape or other cross-sectional shapes.

The first link part 278 may be unfolded or folded by operating inconjunction with the rectilinear movement of the rectilinearly movablemember 276, thereby rectilinearly moving the first touch tip 250 in thedirection in which the first touch tip 250 approaches or moves away fromthe second touch tip 260.

The first link part 278 may have various structures in accordance withrequired conditions and design specifications. The present disclosure isnot restricted or limited by the structure of the first link part 278.

For example, the first link part 278 may include a first idle linkmember 278 a rotatably connected to the base part 272, a first drivinglink member 278 b rotatably coupled to the first idle link member 278 aso as to intersect the first idle link member 278 a and having one endrotatably connected to the rectilinearly movable member 276, and a firstsupport link member 278 c connected to any one of the first idle linkmember 278 a and the first driving link member 278 b and configured tosupport the first touch tip 250.

Hereinafter, an example will be described in which the first supportlink member 278 c is connected to the first idle link member 278 a.Alternatively, the first support link member may be connected to thefirst driving link member.

The first idle link member 278 a and the first driving link member 278 bmay be connected to each other to define an approximately ‘X’ shape.When one end of the first driving link member 278 b rectilinearly movesin conjunction with the rectilinear movement of the rectilinearlymovable member 276, the first idle link member 278 a and the firstsupport link member 278 c may rotate in conjunction with the rectilinearmovement of the first driving link member 278 b, thereby rectilinearlymoving the first touch tip 250.

For example, referring to FIGS. 6 and 7 , when the rectilinearly movablemember 276 moves in a direction in which a drive part is extended to theoutside (in a downward direction based on FIG. 7 ), the first drivinglink member 278 b may move in a direction in which one end of the firstdriving link member 278 b approaches one end of the first idle linkmember 278 a (move in a direction in which the other end of the firstdriving link member approaches the other end of the first idle linkmember), and at the same time, the first support link member 278 c isunfolded in a direction in which the first support link member 278 cmoves away from one end of the first driving link member 278 b, suchthat the first touch tip 250 may move away from the second touch tip260.

On the contrary, referring to FIGS. 8 and 9 , when the rectilinearlymovable member 276 moves in a direction in which the drive part isaccommodated (in an upward direction based on FIG. 9 ), the firstdriving link member 278 b moves in a direction in which one end of thefirst driving link member 278 b moves away from one end of the firstidle link member 278 a (moves in a direction in which the other end ofthe first driving link member moves away from the other end of the firstidle link member), and at the same time, the first support link member278 c is folded in a direction in which the first support link member278 c approaches one end of the first driving link member 278 b, suchthat the first touch tip 250 may approach the second touch tip 260.

In particular, the first link part 278 may include a first connectionlink member 278 d having one end connected to the other of the firstidle link member 278 a and the first driving link member 278 b, and theother end connected to the first support link member 278 c. For example,one end of the first connection link member 278 d may be connected tothe first driving link member 278 b, and the other end of the firstconnection link member 278 d may be connected to the first support linkmember 278 c.

Since the first driving link member 278 b and the first support linkmember 278 c are connected through the first connection link member 278d as described above, an unnecessary movement (swaying and vibration) ofthe first support link member 278 c may be minimized. Therefore, it ispossible to obtain an advantageous effect of improving movementstability and reliability of the first touch tip 250.

The second link part 279 is unfolded or folded by operating inconjunction with the rectilinear movement of the rectilinearly movablemember 276, thereby rectilinearly moving the second touch tip 260 in thedirection in which the second touch tip 260 approaches or moves awayfrom the first touch tip 250.

The second link part 279 may have various structures in accordance withrequired conditions and design specifications. The present disclosure isnot restricted or limited by the structure of the second link part 279.

For example, the second link part 279 may include a second idle linkmember 279 a rotatably connected to the base part 272, a second drivinglink member 279 b rotatably coupled to the second idle link member 279 aso as to intersect the second idle link member 279 a and having one endrotatably connected to the rectilinearly movable member 276, and asecond support link member 279 c connected to any one of the second idlelink member 279 a and the second driving link member 279 b andconfigured to support the second touch tip 260.

Hereinafter, an example will be described in which the second supportlink member 279 c is connected to the second idle link member 279 a.Alternatively, the second support link member may be connected to thesecond driving link member.

The second idle link member 279 a and the second driving link member 279b may be connected to each other to define an approximately ‘X’ shape.When one end of the second driving link member 279 b rectilinearly movesin conjunction with the rectilinear movement of the rectilinearlymovable member 276, the second idle link member 279 a and the secondsupport link member 279 c may rotate in conjunction with the rectilinearmovement of the second driving link member 279 b, thereby rectilinearlymoving the second touch tip 260.

For example, referring to FIGS. 6 and 7 , when the rectilinearly movablemember 276 moves in the direction in which the drive part is extended tothe outside (in the downward direction based on FIG. 7 ), the seconddriving link member 279 b may move in a direction in which one end ofthe second driving link member 279 b approaches one end of the secondidle link member 279 a (move in a direction in which the other end ofthe second driving link member 279 b approaches the other end of thesecond idle link member 279 a), and at the same time, the second supportlink member 279 c is unfolded in a direction in which the second supportlink member 279 c moves away from one end of the second driving linkmember 279 b, such that the second touch tip 260 may move away from thefirst touch tip 250.

On the contrary, referring to FIGS. 8 and 9 , when the rectilinearlymovable member 276 moves in the direction in which the drive part isaccommodated (in the upward direction based on FIG. 9 ), the seconddriving link member 279 b may move in a direction in which one end ofthe second driving link member 279 b moves away from one end of thesecond idle link member 279 a (move in a direction in which the otherend of the second driving link member 279 b moves away from the otherend of the second idle link member 279 a), and at the same time, thesecond support link member 279 c is folded in a direction in which thesecond support link member 279 c approaches one end of the seconddriving link member 279 b, such that the second touch tip 260 mayapproach the first touch tip 250.

In particular, the second link part 279 may include a second connectionlink member 279 d having one end connected to the other of the secondidle link member 279 a and the second driving link member 279 b, and theother end connected to the second support link member 279 c. Forexample, one end of the second connection link member 279 d may beconnected to the second driving link member 279 b, and the other end ofthe second connection link member 279 d may be connected to the secondsupport link member 279 c.

Since the second driving link member 279 b and the second support linkmember 279 c are connected through the second connection link member 279d as described above, an unnecessary movement (swaying and vibration) ofthe second support link member 279 c may be minimized. Therefore, it ispossible to obtain an advantageous effect of improving movementstability and reliability of the second touch tip 260.

One end of the first driving link member 278 b maybe rotatably connected to the sliding member 272 b, and one end of thesecond driving link member 279 b may be rotatably connected to thesliding member 272 b.

Since one end of the first driving link member 278 b and one end of thesecond driving link member 279 b are connected to the sliding member 272b which is moved along the sliding rail 272 a by the rectilinearmovement of the rectilinearly movable member 276 as described above, theswaying of the rectilinearly movable member 276 (the swaying of the endof the rectilinearly movable member 276) may be minimized, andunnecessary movements of the first driving link member 278 b and thesecond driving link member 279 b connected to the rectilinearly movablemember 276 may be inhibited. Therefore, it is possible to obtain anadvantageous effect of more effectively inhibiting the swaying andvibration of the first touch tip 250 and second touch tip 260.

The inner display part 330 is disposed inside the camera test chamber310 (e.g., on an inner wall surface) to display video data of the frontcamera FC received from the vehicle. The outer display part 340 isdisposed outside the camera test chamber 310 (e.g., on an outer wallsurface) to branch an output video of the inner display part 330 andallow the output video to be checked from the outside of the camera testchamber 310.

A typical monitor or other display panels may be used as the innerdisplay part 330 and the outer display part 340. The present disclosureis not restricted or limited by the types and structures of the innerdisplay part 330 and the outer display part 340.

The front camera FC (or the rear camera) mounted on the camera mount 320may acquire a video outputted from the inner display part 330.

Meanwhile, FIGS. 17 and 18 are views for explaining a configuration of acontrol table according to the embodiment of the present disclosure.

Referring to FIG. 17 , an evaluation status board 401 displays anevaluation process and results.

Referring to FIG. 18 , the automatic evaluating part 100 is implementedin the form of a personal computer (PC) in the control table 402, and amanual record button 150, a vibration application button 160, and a gearbutton 170 may be mounted on the table.

In addition, AVN/CCP samples for manual input may be mounted on thecontrol table 402.

That is, a manual manipulation device may be manufactured as a separateproduct and mounted on the control table to enable manual manipulationof the built-in video recording device 203 for a vehicle andmanipulation of an LED indicator.

As such, the present disclosure discloses an example of recording andverifying the video output from the display panel by each camera (thefront camera FC and the rear camera RC). However, it is possible toverify video recording by inputting virtual video data (RGB) to a camerareceiving end.

In addition, evaluation is possible even when there is no sample of thevehicle display device 202 (e.g., AVNT), but it can be implemented as aseparate AVNT simulator so that a screen can be outputted when a displaysimulator, which may replace an AVNT product, is developed to beconnected to a built-in camera. In this case, since the separate AVNT isportable, it can be used not only in the evaluation but also in theactual vehicle.

FIGS. 19 and 20 are views schematically illustrating examples ofautomatic evaluation items of the built-in video recording device 203for a vehicle according to the embodiment of the present disclosure.

Referring to FIGS. 19 and 20 , the automatic evaluating part 100 mayperform GUI verification, basic performance verification, recordingquality verification, electrical performance verification, abnormal modeverification, communication performance verification, and the like ofthe built-in video recording device 203 for a vehicle.

The automatic evaluating part 100 may perform evaluation items such asGUI touch evaluation and GUI center control panel (CCP) evaluation forGUI verification.

In addition, the GUI touch evaluation item may include detailedevaluation items such as GUI mode conversion verification, GUI staticfunction verification, GUI dynamic function verification, GUI abnormalcondition verification, and the like.

The static verification function is a test item that verifies the fixedvideo frame in the built-in camera GUI, and the dynamic verificationitem is a test item that determines whether to scroll a video list orplay a video based on a vision technique.

The GUI mode conversion verification is a test item that checks anability to switch panel control between the AVNT and the built-incamera. The GUI mode conversion verification is a test item to checkwhether control authority is normally transferred to the built-in camerathrough signal handshaking between the AVNT and the built-in camerathrough Ethernet or CAN communication when a built-in camera icon in anAVNT menu is touched.

The abnormal test condition is a test item that verifies whether anormal screen is outputted under various abnormal touch conditions byadditionally setting control such as touch interval and simultaneoustouch through touch coordinates or robot arm (the articulated robot 230)by a tester and implements software to automate the above four GUIverification methods.

The automatic evaluating part 100 performs evaluation items such asbooting time evaluation, front/rear time deviation evaluation, emergencydownload function evaluation, recorded file consistency evaluation, FPSperformance evaluation, and mode evaluation before and after customerdelivery, for the basic performance evaluation.

The booting time evaluation item may include detailed evaluation itemssuch as booting time verification for each power condition and bootingtime verification for each key condition.

A booting time indicates a time from a power-off state of the built-incamera to a point of time when a recording operation is possible whenpower is applied.

In this case, when recording is performed, an interior operation LEDindicator of the front camera FC or the built-in camera lights up, andthe automatic evaluating part 100 utilizes this point to monitor apower-off state of the built-in camera (IG OFF && Communication Sleep),and automatically measures a time until the LED indicator turns on afterapplying an ACC/IG power.

In addition, the automatic evaluating part 100 may measure andautomatically record the time from a time of power application to a timeof power application of the built-in camera LED indicator and evaluatethis by measuring the time from the time when power is applied to thetime when power is applied to the built-in camera LED indicator undervarious voltage conditions.

The front/rear time deviation evaluation items may include detailedevaluation items such as front/rear video deviation verification foreach recording type.

To verify the front/rear time deviation, the automatic evaluating part100 may output a timer that is synchronized to the inner display part330 (e.g., the monitor) in the camera test chamber 310 and control thebuilt-in camera to record it, and may automatically extract a recordedfile and obtain the difference between timer time values displayed onthe front/rear video after playback to obtain information related to adeviation of the front/rear recording time.

In addition, the automatic evaluating part 100 may measure thefront/rear video deviation for each recording mode in order to verify afront/rear video recording deviation, and may automatically performregular driving, driving impact, driving manual, regular parking,parking impact, and parking manual recording modes to measure thefront/rear video deviation for each mode.

Particularly, the automatic evaluating part 100 may apply an impact to aG-sensor in the built-in camera using a vibration motor 294 a for impactrecording and perform the impact recording by applying vibrations whenan impact condition is required during automatic evaluation.

The emergency download function evaluation item may include detailedevaluation items such as log text verification and file copyverification.

Emergency download, which is a function that extracts all videos storedby the built-in camera alone at a service center when the AVNT isdamaged after a vehicle accident, is a function that automaticallydownloads all videos to an USB connected to the built-in camera when aspecific power (e.g., B+/IGN/GND, etc.) is applied. Since the automaticevaluating part 100 can control all PINs of the built-in camera, it mayautomatically determine whether all recorded files have been copiednormally by applying power that satisfies a condition to the built-incamera and monitoring whether files are automatically copied to the USB.In this case, a recorded file of a built-in camera dedicated USB can beautomatically copied to the automatic evaluating part 100.

As such, the automatic evaluating part 100 may determine whether allrecorded files are normally copied, may verify text suitability of a logtext file automatically generated during emergency download, and maydetermine whether emergency download is normally performed.

The recording file consistency evaluation item may include detailedevaluation items such as file capacity verification for each recordingtype and file name verification for each recording type. In the case offile capacity suitability, it is an item that automatically determineswhether the specification for the maximum capacity defined for eachrecording mode (regular driving/driving impact/driving manual/regularparking/parking impact/parking manual/time-lapse) is satisfied. Theautomatic evaluating part 100 may automatically extract only capacityinformation of a recorded video by automatically copying the file afterperforming recording with a maximum capacity for each recording mode,may filter the maximum capacity among them, and automatically compareand verify that this maximum capacity meets a specification. Inaddition, the automatic evaluating part 100 may automatically verifywhether the recorded file satisfies a prescribed file name.

The frame per second (FPS) performance evaluation may include detailedevaluation items such as FPS verification for each recording type.

An FPS verification technique for each recording type is a newverification item that was not performed during actual vehicleverification. The automatic evaluating part 100 may record all videosfor each recording mode in a full memory, and then may play eachrecorded file and extract the number of frames per second in real time,and may finally record Max FPS, Min FPS and Avg FPS valuesautomatically.

The automatic evaluating part 100 may automatically calculate how muchthe Max FPS, Min FPS, and Avg FPS values exceed or dissatisfy an FPScriterion for each recording mode defined in the specification andautomatically determine that it is a failure when it is less than theset criterion (tolerance).

The mode evaluation item before and after customer delivery may includedetailed evaluation items such as operation evaluation before and aftercustomer delivery.

The automatic evaluating part 100 may perform a camera visibilityevaluation item to verify recording quality. The camera visibilityevaluation item may include detailed evaluation items such as licenseplate video visibility verification.

For license plate visibility verification, the automatic evaluating part100 may output the license plate to the front/rear camera test parts300, 300′ on the display panel, may gradually reduce a size from anactual size of the license plate, and may evaluate it by estimating adistance to the actual vehicle. The automatic evaluating part 100 may beprovided with an illuminance control function on the display panel(monitor) itself of the front/rear camera test parts 300, 300′ andautomatically adjust brightness and may automatically verify licenseplate visibility by various an illuminance condition and estimateddistance from the actual vehicle.

The automatic evaluating part 100 may perform evaluation items such asoperating voltage evaluation and consumption current measurement toverify electrical performance.

The operating voltage evaluation item may include detailed evaluationitems such as undervoltage evaluation and overvoltage evaluation. Inthis case, the consumption current measurement item may include detailedevaluation items such as controller consumption current measurement andauxiliary battery consumption current measurement.

The automatic evaluating part 100 may perform evaluation items such asan abnormal power mode, an abnormal key mode, an abnormal eventapplication mode, and an abnormal combination condition mode forabnormal mode verification.

The abnormal power mode may include detailed evaluation items such asverification of a startup waveform influence and an abnormal waveforminfluence.

When verifying the abnormal power mode, the automatic evaluating part100 may perform evaluation after presetting various abnormal powerconditions in a graph form using the power supply part 180.

The automatic evaluating part 100 may apply a waveform such as a vehiclestartup waveform or instantaneous power drop to the built-in cameraduring an operation of the built-in camera to determine whetherrecording is normally performed and whether there is a malfunction. Inthis case, the automatic evaluating part 100 may automatically determinewhether recording is normally performed using whether an LED indicatoris lit during recording and whether a built-in camera GUI menu isnormally outputted. In addition, the automatic evaluating part 100 mayperiodically transmit a fault diagnosis request (Tx) message to thebuilt-in camera through a communication line of the built-in camera, andwhen a fault code response occurs, may record it and automaticallydetermine whether there is a fault.

The abnormal key mode may include detailed evaluation items such as keyon/off repeated verification and mode change overlap verification.

The abnormal event application mode may include detailed evaluationitems such as impact application repeated verification, manual switchrepeated verification, and mode change overlap verification.

The abnormal combination condition mode may include detailed evaluationitems such as key and GUI, key and event, GUI and event, network sleepand key, and network sleep and event.

For the abnormal combination condition mode verification, the automaticevaluating part 100 may automatically verify whether the built-in cameramalfunctions under various abnormal conditions by combining a built-incamera power condition (B+/ACC/IG1), a GUI touch condition, and animpact application condition.

The automatic evaluating part 100 may determine whether it is normal byautomatically measuring an LED indicator, a GUI menu normal output, afault code occurrence, etc. after each of the abnormal conditions isapplied, similarly to the power malicious mode verification.

The automatic evaluating part 100 may perform evaluation items such asdiagnostic communication evaluation, fault diagnosis evaluation,controller communication performance evaluation, and auxiliary batterycommunication performance evaluation for communication performanceverification.

The diagnostic communication evaluation may include detailed evaluationitems such as UDS on CAN reprogram evaluation and OBD standardizationlaw evaluation.

The failure diagnosis evaluation may include detailed evaluation itemssuch as various failure diagnosis evaluations. The controllercommunication performance evaluation may include detailed evaluationitems such as CAN evaluation (high/low speed) and Ethernet communicationperformance evaluation. The auxiliary battery communication performanceevaluation may include detailed evaluation items such as LIN evaluation.

Meanwhile, a GUI touch automatic evaluation technique may be classifiedinto two main methods. A first one thereof is a technique to virtuallytransmit touch coordinate information to the built-in camera controllerto determine the transmitted GUI video when there is no AVNT sample. Asecond one thereof is a technique to determine a video by directlytouching a AVNT panel with a robot arm (the articulated robot 230) bymounting an AVNT sample.

First, when there is no AVNT sample, a method of performing automaticsimulation evaluation by inputting virtual touch coordinates instead ofcontrol of the robot arm (the articulated robot 230) is disclosed.

The automatic evaluating part 100 may learn GUI coordinates and videosthat are determination criteria by virtually inputting touchcoordinates. That is, the automatic evaluating part 100 does not have anAVNT sample and the robot arm (the articulated robot 230), but learnsand stores coordinate information and a video executed by the touch inadvance when the robot arm (the articulated robot 230) actually touchesthe AVNT.

Since the GUI specification transmitted by the built-in camera, which isthe built-in video recording device, differ for each AVNT specification,it implements a function of acquiring and learning a video that is adetermination criterion based on a AVNT platform.

That is, the automatic evaluating part 100 may learn in advance GUIcoordinates and videos, which are determination criteria for automaticevaluation of the built-in video recording device 203 for a vehicle.

The automatic evaluating part 100 outputs a GUI branch screen of thebuilt-in video recording device 203 (e.g., the built-in camera) for avehicle, and outputs a topmost screen among the built-in camera menus.Next, it sets a function by touching each function tab in the topmostscreen, learns and stores coordinate information related to thefunction. Specifically, when a user clicks a menu tab and a recordinglist tab on the AVN screen, coordinate information and a video to beexecuted may be learned and stored as a determination reference video.

In addition, the automatic evaluating part 100 may output a detailedscreen when a menu tab or a recording list tab is clicked, may learn andsave coordinate information by clicking a detailed menu tab (e.g., acopy tab, a delete tab, or a setting tab) on a detailed screen, and mayoutput a more detailed menu when each detailed menu tab is clicked. Itis possible to enter the GUI such as 1^(st) Depth, 2^(nd) Depth, 3^(rd)Depth from a GUI main menu through touch automation for each test item,and it makes it possible to return to Default Depth (main menu) when anindependent test is performed.

As described above, the automatic evaluating part 100 may learn andstore in advance coordinate information and a determination referencevideo when the menu tab is touched by a user.

The automatic evaluating part 100 selects an evaluation item of thebuilt-in video recording device 203 for a vehicle as illustrated inFIGS. 19 and 20 for evaluation and starts the evaluation.

Then, the automatic evaluating part 100 may determine the evaluation inreal time.

In this case, the automatic evaluating part 100 may compare a videotransmitted from the built-in video recording device 203 (e.g., thebuilt-in camera) for a vehicle to the vehicle display device 202 (e.g.,AVNT) with the determination criterion video data to automaticallydetermine whether the corresponding video data is normal. In this case,the automatic evaluating part 100 may branch-acquire low voltagedifferential signaling (LVDS) communication or Ethernet communicationdata and compare it with determination reference video data to performautomatic determination.

In addition, the automatic evaluating part 100 may output thebranch-acquired LVDS (low voltage differential signaling) communicationor Ethernet communication data to a situation monitor so that a user canvisually determine whether it is normal.

The automatic evaluating part 100 ends the evaluation after automaticdetermination, automatically outputs a report on the evaluation, andperforms log recording.

Meanwhile, when there is the AVNT sample, the evaluation may beperformed by touching the AVNT screen by controlling the robot arm (thearticulated robot 230).

The automatic evaluating part 100 may learn coordinates of a positiontouched by the robot arm and the video used as the determinationcriterion. That is, the automatic evaluating part 100 may control therobot arm (the articulated robot 230) to touch the AVNT sample. When therobot arm (the articulated robot 230) touches the AVNT sample, theautomatic evaluating part 100 may learn and store coordinate informationand videos executed by touch in advance.

As described above, the automatic evaluating part 100 may learn andstore in advance coordinate information and a determination referencevideo when the menu tab is touched by the user.

The automatic evaluating part 100 selects an evaluation item of thebuilt-in video recording device 203 for a vehicle as illustrated inFIGS. 19 and 20 for evaluation and starts the evaluation.

Then, the automatic evaluating part 100 may determine the evaluation inreal time.

In this case, the automatic evaluating part 100 may compare a videotransmitted from the built-in video recording device 203 (e.g., thebuilt-in camera) for a vehicle to the vehicle display device 202 (e.g.,AVNT) with the determination criterion video data to automaticallydetermine whether the corresponding video data is normal. In this case,the automatic evaluating part 100 may branch-acquire low voltagedifferential signaling (LVDS) communication or Ethernet communicationdata and compare it with determination reference video data to performautomatic determination.

In addition, the automatic evaluating part 100 may output thebranch-acquired LVDS (low voltage differential signaling) communicationor Ethernet communication data to a situation monitor so that a user canvisually determine whether it is normal.

The automatic evaluating part 100 ends the evaluation after automaticdetermination, automatically outputs a report on the evaluation, andperforms log recording.

The built-in camera transmits a setting GUI and playback GUI to the AVNTpanel using LVDS communication or Ethernet communication. Accordingly,the automatic evaluating part 100 may branch a video communication linebetween the AVNT and the built-in camera to branch and output the videotransmitted from the built-in camera to the AVNT to the display part 130of the automatic evaluating part 100.

Therefore, when performing initial test scenario and a determinationscreen learning process through a screen of the branched video, a usermay learn a test sequence such that the test proceeds in an order inwhich the displayed GUI touch is touched with a mouse, and may storescreen information that is outputted every time it is touched toimplement it to be used as a comparison determination screen duringactual automatic evaluation.

First, for each GUI platform specification, a tester captures and learnsthe test scenario and a determination criterion screen once, and thenautomatic evaluation is possible between the AVNT and the built-incamera of a same platform.

After scenario learning, it is possible to perform evaluation byseparating a case that the aforementioned AVNT sample exists and a casethat no AVNT sample exists. Accordingly, when the AVNT sample and therobot arm exist, the automatic evaluating part 100 may automaticallydetermine whether or not it is a valid GUI output or not through GUIdata that the robot arm (the articulated robot 230) directly touches theAVNT screen according to the scenario and branches at the same time.

As illustrated in FIGS. 6 to 11 , the electrostatic touch unit 240 mayinclude first touch tip 250 and second touch tip 260, and it is possibleto evaluate an enlargement/reduction function of a playback screen inthe same way as control through human fingers by addingenlarging/reducing control function to the first touch tip 250 andsecond touch tip 260. In addition, since the robot arm (the articulatedrobot 230) is equipped with a high-performance camera (the GUI testcamera 280), the video outputted from the AVNT panel can be comparedwith the GUI transmitted from the built-in camera, and thus the built-incamera and the AVNT output GUI may be compared and determined.

When there is no AVNT sample, the automatic evaluating part 100 mayautomatically input virtual touch coordinate information to the built-incamera through LVDS or Ethernet communication to determine a screenbased on GUI information outputted from the built-in camera.

As such, when there is no AVNT sample, built-in camera GUI software isindependently verified, and when there is an AVNT sample, the built-incamera GUI software and the AVNT software can be compared and verifiedat the same time.

As such, according to the present disclosure, through development of abuilt-in camera system level automating evaluation device, GUI touchtest may be quantified using robot arm control or automatic touchcoordinate input software, and recording file full loading evaluationmay be performed automatically. In addition, according to the presentdisclosure, various evaluations may be performed without time and spaceconstraints by implementing quantitative test control for illuminanceand license plate distance control, which was previously difficult tocheck under actual vehicle environmental conditions. In addition, thepresent disclosure can also be used for single item verification bypartners who will develop our built-in camera system in the future andalso be usefully used for local development in overseas technicalresearch institutes.
